LEA’S OAK. 
QUERCUS Leana, foliis membranaceis, longissime petio- 
latis, oblongo-ovalibus, basi rotundatis, subcordatis, sinu- 
ato-pinnatifidis, demum glabris, lobis latis integris setaceo- 
acuminatis ; fructibus brevi-pedicellatis; solitariis binisve, 
cupula hemispherica, squamis ovalis obtusis, glande sub- 
globosa vittata subsemi-immensa, cum umbone brevi conico. 
Of this remarkably ambiguous Oak I have already 
spoken, in a note on Q. heteropliylla , having at that time, 
in concert with Mr. Thomas G. Lea, its discoverer, con- 
sidered it as a variety of that rare species or some 
analogous hybrid. Other specimens, accompanied with 
the ripe glands, have now convinced me that it is either 
a distinct species or another strange hybrid; but as I 
am by no means satisfied of the existence of such spon- 
taneous mixed races among our Oaks, I have taken the 
liberty of giving it as a species, and dedicating it to its 
discoverer, an ardent and successful botanist. I shall 
also take the liberty of adding a quotation from Mr. 
Lea’s notes, made on this plant, and sent to me with the 
specimens. 
“The fruit resembles Michaux’s figure of Q. hetero- 
phylla , but differs in being more depressed and obtuse at 
the summit. The cups, I think, are alike. The leaves 
are on longer petioles, but accord in being inclined to be 
cordate at base. If it is a hybrid, it may have come 
from the Q. imbricaria or Q. tindoria or Q. coccinea. 
The fruit is too widely different from Q. rubra. The 
peduncles are about the same length as in my specimens 
of Q. imbricaria ; in Michaux’s figure of that species the 
fruit is represented as sessile , which I think is wrong. 
The petioles are much longer than in Q. imbricaria , the
